Sleep is an important part of our daily routine. we spend about one-third of our time doing it. Quality sleep and getting enough of it at the right times is as essential to survival as food and water. Without sleep we can’t form or maintain the pathways in our brain that let us learn and create new memories, and it’s harder to concentrate and respond quickly.
Most people think that when they sleep, their brain sleeps too. But it turns out that parts of the brain are more active (several times) overnight than during the day. One of these is a newly discovered system called SYSTEM GLYMPHATIC, Health "in the" city of the brain, "the function of scanning and refining all the toxins in your brain. One protein that is effectively re-refined during sleep is responsible for amyloid deposition, the hallmark of Alzheimer's disease. Of course, this does not mean that Alzheimer's is caused by sleep deprivation, but it may be a contributing factor.
No doubt, less sleep time deteriorates brain activity and retards mental speed
The lack of accumulated sleep has real and serious effects on the brain, not just because it makes you feel sleepy all day long.
Sleep has been linked to less than seven or eight hours per night with cognitive decline, memory loss, and possibly even Alzheimer's disease.
Every working machine needs a rest. Brain needs to be rested and the only way to achieve that is through sleep. Lack of enough rest has negative effect on brain and human's health in general.
In Lack of Sleep, brain starts eating itself leads to several pchycological problems .
Sleep rejuvenates human brain during which proper hormones are secreted. Analogically, it is comparable to a mobile battery which needs to be charged in order to be functional.
Yes, sleep affect the activities of brain and every person should try to get the minimum required sleeping hours per day for betterment of brain neuron functions.
Little sleep hours affect brain function and make the human concentration less as well as many sleep hours have the same effect
Of course dear Marianne Levon Shahsuvaryan lack of sleep affects brain activity.
As you sleep, memories are reactivated, connections between brain cells are strengthened, and information is transferred from short to long-term. Without enough quality sleep, we can become more forgetful. Studies suggest that sleeping shortly after we learn new information helps us retain and recall that information later.
A joint team of neuroscientists at the Italian Polytechnic and Padova Universities and the University of Wisconsin in the United States published the findings in the Journal of Neuroscience in May. The study relied on follow-up samples of mice, based on their periods of sleep, and observed an unusual activity in the astrocytes of the brain in mice deprived of sleep, unlike mice that slept normally for 7 to 8 hours a night. "Stellar cells usually clean the brain by removing the products of nerve erosion during the day," says Michel Pilsy, professor of physiology and neuroscience at Italian Polytechnic University and head of the research team. But when there is a lack of sleep rates, these cells eat the points of engagement, that is, the brain begins to hurt himself instead of cleaning himself! "Wael Abu Hindi - Professor of Psychiatry, Faculty of Medicine, Zagazig University, told" Science "that Stellar cells are one of four types of glial cells found in the central nervous system: astrocytes, dendritic cells, endothelial cells, and microglia. "Stellar cells are small astrocytes that spread in the tissue of the nervous system Central, where it maintains the integrity of the cerebral hemangiomas which prevents The arrival of harmful chemicals and bacteria to the center of control in our body. "He adds: This type of cells can absorb and store and then secretion of some neurotransmitters, which makes them important in the chemical conduction of the nervous system within the central nervous system The risk of Alzheimer's and although eating synapses It is not necessarily harmful, as it may be a cleaning process within the brain, which is similar to the process of disposal of old furniture at home, but lack of sleep stimulates glial cells, which is strongly active in the brains of people with Alzheimer's disease. "There is evidence that the persistence of glial cells in their activity at a low rate leads to brain disorders and leads to the accumulation of beta amyloid acids that block the blanks between the brain cells," he says. "The accumulation of amyloid acids is a major contributor to Alzheimer's disease, accumulating in large quantities in the brain, gradually destroying nerve cells and cutting off their connections to neighboring proxies," he said. "These numbers are larger in acute cases of Alzheimer's disease." The brain of amyloid beta, it accumulates in the form of plaques that destroy the synapses that link between neurons, leading to a deterioration in the cognitive capacity of the patient and his loss of memory On the symptoms that indicate the exposure of the brain to erosion, Belsey confirms that "there are no specific symptoms, "The mice that underwent the tests showed no kind of altered behavior but a desire to resist going to sleep." Belsey advises that "sleep well and adequately, as it is essential for the brain and body together." Lack of dream and increased anxiety With regard to some negative psychological and physical effects Which may result from the lack of hours of sleep, says Adel Kamal - professor of clinical psychology and psychological analysis at the Faculty of Arts at the University of Banha - for "science:" The lack of sleep has severe negative effects on the psychological state of the person, It limits people's ability to dream as a means of coping Li excess tension and shipments of concern and to compensate the person desires to meet pent-up deficit, so the lack of sleep lead to the absence of a dream and increased anxiety and mental disorders, and the subsequent increased risk of exposure to physical diseases. " A previous study by a team of researchers at the Pennsylvania School of Medicine warned that a lack of sleep would "double the risk of death from myocardial infarction or stroke in people who are at risk for many cardiovascular risks, including obesity and high blood pressure And the rate of excess cholesterol or diabetes. In their study, which was based on a random selection of 1,344 adults with an average age of 49 years, 42% of them reported that "the results of tests and tests showed that more than 39% of the participants had at least three risk factors In a follow-up period of more than 16 years on average, 22% of the study subjects died, and those with metabolic syndrome who slept less than six hours In the laboratory, odds are 2.1 times greater for death from a heart attack or gel A study conducted by a team of researchers at the University of Uppsala, Sweden, headed by Dr. "Jonathan Sideras" that people who sleep very short periods up to about 4 hours, they have harmful bacteria in the intestine, damage beneficial bacteria, and cause many of the risks, including: - Violation of bacterial balance in the intestine. - Changes related to the conditions of the metabolic mechanism, including obesity and high risk of diabetes. - People who are deprived of sleep become less sensitive to the effects of the insulin hormone important to the pancreas, which helps regulate blood sugar levels. - Increased fat mass, intestinal permeability and inflammatory reactions, especially in adipose tissue. - Hypertension. - Increased rates of risk of cardiovascular disease, mainly blockage of arteries and weakness
Decreased memory: It is one of the most important effects of lack of sleep on the brain, where lack of sleep to reduce the activity of brain cells responsible for memory, which limits the ability to remember people's names or things, or forget some appointments
Sleep has large impact on all our brain work. A good sleep improves and boosts memory, thinking capacity and many other brain functions. Contrarily, lack of sleep harms the whole bodily functions, and impact intensifies with time. Hence, people engaged in intellectual work, must pay attention to their sleeping habits.
Lack of sleep can cause all kinds of health problems including memory issues and the person can make many mistakes (for example while driving or doing intricate work that requires concentration). About 8 h/night is needed. A power nap lasting no more than 30 minutes in the afternoon helps refresh a person considerably including their brain.
Yes, sleep affect the activity of brain. It is also variable according to different person. For me, I need 6-8 hours daily and if I sleep more than 9 hours, I use to have migraine attack. Some professionals like pilots used to sleep for lesser hours than average, and their brain activity is still normal.
Yes sure ... Djaafar Zemali Lack of sleep affects the memory ... Greetings
Thank you dear Dr Sanatombi Devi Yumkham. On your answer .. I hope you good luck
Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. In fact, your brain and body stay remarkably active while you sleep. Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake.
Sleep is one of the most important physiological needs of humans. It works to renew mental activity and improve human ability to cognition, The lack of sleep causes several damage that negatively affects the brain, including poor memory, slow absorption, erosion of brain cells
Sleep is an important daily activity for human. However, sleep less than 6 hours or more than 8 hours disturb our body and brain as we'll.
Inadequate sleep impairs the hippocampus, the major brain structure that is responsible for learning and memory formation. Thus sleep deprivation negatively affects the academic performance and learning. Receiving enough sleep does not only help the brain to function properly, but also has a positive impact on our lifespan and is imperative in maintaining a good health.

Of course yes! I don't know the mechanism but I feel more refreshed and work/concentrate better in the early hours after sleeping.
Sleep deprivation reduces learning, impairs performance in cognitive tests, prolongs reaction times and is a common cause of seizures.
Chronic disruption of sleep has serious implications for health – it disrupts metabolic processes, adversely affects cardiovascular functions, increases blood pressure, may cause irregular heart beat and increases the likelihood of diabetes and stroke.
It can also negatively influence stress hormones, immune function, weight maintenance and mental health.
It was observed that during wakefulness, the brain accumulates toxins which are cleared during sleep. There is a strong suggestion at this time that lack of sleep is an important factor in causing neurodegenerative diseases.
Sleep deprivation has direct effects on your brain. People who are suffering from sleep deprivation work less effectively and become less productive over periods of time. It is extremely important to have quality sleep in order for your brain and body functions to run appropriately.

Definitely Zacari Djaafar Zemali sleep is important for a number of brain functions ... Thank you
Yes Dear Nadeen Mohammed Sleep Improving the human ability to cognition ... Thank you
Yes Dear Dawood Mahdi You should not sleep less than 6 hours and not more than 8 hours and this time is good for the work and brain activity .... Thank you
Certainly Arvind Singh. Sleep deprivation negatively affects academic performance ... Thank you and greetings
Yes, Dr. Felix Nwafor improves performance and work better after taking enough sleep. Thank you and greetings
I agree with you Sadanand Pandey. Sleep deprivation affects health in general. Thank you
in the study, the researchers found that sleep deprivation makes it difficult for brain cells to communicate effectively, which, in turn, can lead to temporary mental lapses that affect memory and visual perception.
In other words, the findings offer clues as to why a sleepless night makes it so hard to think and concentrate the next day.
A recent study shows that sleep for sufficient hours positively affects the function of T cells, thus enhancing the immune system, fighting germs and fighting the growth of cancer cells in the body. And that lack of sleep may cause multiple health problems.
Thank you to all the teachers for the useful answers and wonderful .. Greetings
Recent research has shown that lack of accumulated sleep has real and serious effects on the brain, not just because it makes you feel drowsy all day long. Sleep has been linked to less than seven or eight hours per night with cognitive decline, memory loss, and possibly even Alzheimer's disease, said Dr. Morali Duraiswamy, a brain disease researcher from Duke University in North Carolina. Most people think that when they sleep, their brain sleeps too, but it turns out that areas of the brain are more active (several times) during the night than during the day. One of these aspects is a newly discovered system called the SYSTEM GLYMPHATIC, a type of "sewage" in the "brain city", whose function is to scan and refine all your brainworms. One protein that is effectively re-refined during sleep is responsible for amyloid deposition, the hallmark of Alzheimer's disease. Of course, this does not mean that Alzheimer's is caused by sleep deprivation, but it may be a contributing factor. 2. Repair of damage resulting from daily use A new study suggests that chronic sleep deprivation can lead to irreversible damage to brain tissue. In a study of animals at the University of Pennsylvania, researchers found that prolonged vigilance could hurt nerve cells responsible for alertness and perception, and that damage could always be. Insufficient sleep can also be linked to shrinking the size of the brain over time (although it is not clear whether lack of sleep causes brain contraction or if the smaller brain makes sleep more difficult). Other studies have led scientists to conclude that chemicals released during the deep stages of sleep are essential for the repair of all tissues of the body, including the brain. 3 - Arrange "chaos" in the brain While you are preoccupied with your daily activities, your brain is exposed to thousands of stimuli audio, visual, nervous and sensory .. It is not usually possible to address all that information mentally if it comes .. So classifies and "tattoos" a lot of memories at night while Sleeping, this is somewhat like what happens in libraries .. All the books that remain on the library tables during the day dust is removed and classified at night. People who think they adapt well to sleep for only four or five hours are often mistaken because memory tests show they do not work best because of the accumulation of information that their brain has not been able to arrange at night. 4. Creating memories One of the chemicals that contribute to the creation of memories is called "acetylcholine," and surprisingly, this same article contributes to bringing sleep and making dreams come true. Perhaps what happens to people who start Alzheimer's disease is an indication of the importance of the role of sleep in retaining and creating memories. With this disease, the brain cells that produce acetylcholine are destroyed, so the sufferers stop dreaming! Interestingly, the side effects of the drug most commonly used in the treatment of Alzheimer's disease - arispt drug - its ability to create powerful dreams effect.
Thank you very much Professor Muhammad Abdullah Avais ... I agree with you ... Greetings
Certainly lack of sleep leads to many diseases and weaken the immunity of the body
One of the central functions of sleep is that it helps consolidate long-term memory—it seems to do this, not only through strengthening certain neural connections, but also through pruning back unwanted ones. The brain makes a lot of connections during the day, but not all of them are worth saving; so sleep is a time in which the brain streamlines the connections it “needs.”
